Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest point of the building, irrespective of material or function of the highest element (i.e., including antennae, flagpoles, signage and other functional-technical equipment).
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the architectural top of the building, including spires, but not including antennae, signage, flag poles or other functional-technical equipment. This measurement is the most widely utilized and is employed to define the Council on Tall Buildings and Urban Habitat (CTBUH) rankings of the "World's Tallest Buildings."
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest occupied floor within the building.
The number of floors above ground should include the ground floor level and be the number of main floors above ground, including any significant mezzanine floors and major mechanical plant floors. Mechanical mezzanines should not be included if they have a significantly smaller floor area than the major floors below. Similarly, mechanical penthouses or plant rooms protruding above the general roof area should not be counted. Note: CTBUH floor counts may differ from published accounts, as it is common in some regions of the world for certain floor levels not to be included (e.g., the level 4, 14, 24, etc. in Hong Kong).
The number of floors below ground should include all major floors located below the ground floor level.

Usually involved in the front end design, with a "typical" condition being that of a leadership role through either Schematic Design or Design Development, and then a monitoring role through the CD and CA phases.
The Design Engineer is usually involved in the front end design, typically taking the leadership role in the Schematic Design and Design Development, and then a monitoring role through the CD and CA phases.
Other Consultant refers to other organizations which provided significant consultation services for a building project (e.g. wind consultants, environmental consultants, fire and life safety consultants, etc).
These are firms that consult on the design of a building's façade. May often be referred to as "Cladding," "Envelope," "Exterior Wall," or "Curtain Wall" Consultant, however, for consistency CTBUH uses the term "Façade Consultant" exclusively.
Material Supplier refers to organizations which supplied significant systems/materials for a building project (e.g. elevator suppliers, facade suppliers, etc).

EMI Lead Chicago Tall-Building Study Trip
25 May 2015 - Event
Visit to the 300 North LaSalle Tower, Chicago
3 November 2010 - Event
Comprised of office, retail, restaurant, amenity and public spaces as well as below-grade parking, 300 North LaSalle re-establishes a pedestrian connection to the city, featuring a half acre waterfront public garden with direct access to the river and views of the city. The thoughtful placement of the tower’s rectangular form on the northern limit of its site maximizes the southern exposure of the public garden whilst minimizing solar gain on the narrower east and west façades. An asset for this area of Chicago, this public space enhances the streetscape at the base of the LaSalle Street Bridge and cascades to the river with a fine dining restaurant, landscaped terraced seating and a waterfront café.
The tower’s design accommodates efficiency and flexibility in interior planning and its floor-to-ceiling glass provides abundant natural light and dramatic views. The transparency and luminosity of its façade create a lighter, delicate silhouette. A desire for a modern image anchored in the past informed the design that recalls the Chicago Miesian tradition as well as art deco stepped skyscrapers. The elegant, three-story lobby features a decorative screen of cherry wood and ornamental stainless steel, set off by a floor of golden limestone. The tower culminates with a luminous, articulated stainless steel crown which acts as a beacon along the Chicago River.
The building’s façade of clear low-E glass and stainless steel shading fins maximizes daylight while mitigating solar heat gain. The tower uses condenser water supplied by the Chicago River to reject heat from the chilled water air conditioning system and eliminate the need for cooling towers, make-up water and chemicals, thus eliminating 10 million gallons of evaporation annually.
